I have a small plaster repair job coming up. It’s big enough for everyone to tell me to use drywall mud, but that doesn’t seem to capish with old plaster walls. The only thing is that I am NO GOOD at plaster (except for making casts or something), I always get half way into a batch when the stuff starts to set-up leaving me smearing half hardened plaster on and going back with a sponge. Maybe I’m using the wrong type (moulding plaster) or maybe there is a chemical, animal or vegetable out there that once added will slow the set-rate down (or the pot-life as it were)to a more reasonable level. Or maybe I should just hire a plater man and keep my tool belt on in the name of all things wooden. Suggestions, anyone?

*you just got it. Cream of Tartar acts as a retardent, so does sugar.

In the old country, me grandpa used goat poops .He swore by it. I could never find any of it in N.Y.C. . Try some white vinegar , it doesn't smeel as good but slows the drying time .
*ClayYou dont say what background you are applying the plaster on,If it is solid masonry,then apply a coat of white PVA adhesive mixed 1 part to 5 parts water and allow to dry (15 mins)this not only aids the adhesion to the wall but extends the setting process by eliminating the suction from the masonry Also try calling your USG rep re masonry plasters

So... you stole my answer Joe. Brewskie will give him more than enough to ponder!

Mr Mcgough,
Please accept my sincerest apologies. I somehow read your response somehow as Tartar sauce. Guess I need to go back to eatin' fish (or else crow).

No apology necessary clay. You wouldn't be the first to think I was joking. Now wait til I recommend a couple of shovels of dirt or chicken manure to accelerate the concrete.
BTW, good luck in the Big Apple. Stay put until you have a place to stay. Better late than sorry.
